Audio books filed in "Unknown" folder

OK, you’ve got me a little confused. 

Are you looking at the display on the player, or are you looking at the folders in your computer?

If on the player, are you navigating through Folders (way down the scroll in Music past Album, Artist, etc.)? Or through Audiobooks?  Audiobooks is navigating by tags. Folders should work like Windows Explorer, with folders and subfolders. 

The tags wil be (or should be) what the player displays. If Album doesn’t do it, try mp3tag for Artist (and make that the author). Make sure you are changing the tags in the copy on the player. Sometimes I have done a bunch of re-tagging only to find that I was changing the ones on my computer, not the player. D’oh. 

Mp3Tag won’t change the name of the folder in your computer. How about a folder name that’s just alphanumeric, no spaces, punctuation, etc.
